UNITED STATES PATENT oFFio CHARLES H. JOHNSON, OF BOSTON, MASSACHUSETTS.

GAS-BURNER.

Specification forming part of Letters Patent No. 13,130, dated June 26, 1855; Reissued June 2, 1857, No. 467.

To all whom it may concern Be it known that I, CHARLES H. JoHNsoN, of Boston, in the county of Suffolk and State of Massachusetts, have invented a new and useful Improvement in Gas-Burners; and I do hereby declare that the same is fully described and represented in the following specification and the accompanying drawings, letters, figures, and references thereof.

Of the said drawings Figure 1, exhibits an external View of one of my improved burners. Fig. 2, is a vertical and central section of the same; Fig. 3, is a side view of its distributer and purifier; Fig. 4, is an underside View of said distributer and purifier.

The said gas burner is constructed with a cylindrical chamber, A, into which the gas is received through a small gage hole or orifice, a, formed through the bottom, 6, of said chamber. l/Vithin this chamber there is arranged a hollow cone distributer B, which is open at its lower end and contains a series of wires as seen at O, they being arranged somewhat like the bristles of a brush and made to extend downward from the vertex of the cone and to constitute a purifier or a means of dividing or purifying the gas or separating from it much foreign matter, which if consumed with the gas would be detrimental to its light giving property.

The upper part of the distributer B, is fastened to a diaphragm or plate D, which is perforated so as to permit gas to freely pass through it and into a tapering or bell mouth chamber, E, arranged over the chamher and between it and the discharging mouth or mouths, O, O, of the burner. This diaphragm is forced up against the top of the chamber, A, by means of a spring, F, which is arranged within the distributer and presses against the bottom of the chamber A. The base of the distributer I provide with a fianch as seen at d, d, whose external edge is serrated or notched as seen at, e, e, the object of the fianch being to centralize the distributer within the chamber, such distributer when in use being somewhat elevated above the bottom of said chamber.

In the operation of a burner so constructed, the gas on entering it passes and flows, among the wires of the purifier and by means of the distributing cone is reverberated and thrown outward and made to pass underneath the fianch, (Z, and upward into the chamber, A. From whence it fiows through the plate or diaphragm D, and into the tapering or gathering chamber, E, placed over the same. By means of this last named chamber, the streams of gas are caused to gradually approach one another and flow freely toward the discharging orifices without such injurious impingement against one another, as will produce a flickering of the flame.

By means of the tapering chamber, great steadiness of" the fiame is obtained. When the distributer and purifier are used a very important change in the color of the flame takes place, and it is found that scarcely any tar or foreign matter is received into the main part of the chamber, A, and the burner.

hat I claim is combining the gas distributer and purifier B as herein described with the burner so as to operate therewith substantially as set forth.

In testimony whereof I have hereunto set my signature this twenty eighth day of April CHARLES H. JOHNSON. Witnesses:
